Thanks. But is it safe to shine all that power in the ear? 20W sounds a lot. Anything above 500mw could cause damage.
Also how would you assemble it, i dont have experience doing that, is there a dummys guide?
Hi,
Has anyone looked at the device below? It seems powerful 200mw, and not too expensive
